AI Technical Summary
Technical Problem
Existing surgical procedures like Roux-en-Y gastric bypass carry significant health risks and there is a need for a non-invasive endoscopic method to achieve similar metabolic effects.
Method used
A barrier device comprising a tubular barrier with self-expanding stents at the proximal and distal ends, anchored by an anchoring stent, is delivered via a catheter using peristalsis to mimic gastric anatomy and reduce nutrient absorption in the GI tract.
Benefits of technology
The device effectively reduces nutrient absorption without invasive surgery, aiding in weight loss and maintaining natural GI tract anatomy.

Abstract
The present invention relates to a barrier device, comprising a distal self-expanding stent having a ring-like structure in an expanded configuration, a tubular barrier having a proximal end, a distal end, and a lumen extending therethrough, the distal self-expanding stent disposed at the distal end of the tubular barrier, and an anchoring self-expanding stent disposed at the proximal end of the tubular barrier, wherein the distal self-expanding stent is configured to get distally translated through the intestine by peristalsis.
